BUT today with the z6/z7 i really feel left behind.
I don't. I'm bored with mirrorless hype.
What does mirrorless really, truly bring to the table?
- Size and weight savings, but only with smaller sensors. With FF the differences are insignificant.
- EVF. I admit I think live exposure preview is useful, but EVFs still can't touch OVFs for overall viewing experience.
- Potentially faster fps / quieter shooting. But few bodies have realized this potential.
Other than that? Adapter headaches and more things to buy.
To the degree that the z7 is a "better" camera than my 5Ds it is so for the same reason as the D850: it was released much later. And you'll notice that I have "better" in quotes because while I acknowledge the video gains, faster fps, and greater DR, none of those things would really affect my photography. (I'm interested in stills so the gap in video is irrelevant to me.)
I am interested in seeing what Canon does for FF mirrorless. But even if Canon took another two years to release a FF MILC body I wouldn't be tempted to switch brands. (I doubt they'll do this. I think we'll see the first Canon FF MILC in early 2019.)
I don't get the hype at all. Honestly something like the M5 or the Fuji system have more appeal to me as a 2nd lightweight kit. I'm not interested in FF mirrorless at all.
